Specification of Letters Patent.

Patented Mar. 28, 1911.

Application filed April 30, 1910. Serial No. 558,555.

To all whom it may concern:

-Be it known that I, HARRY W. Woon, a citizen of the United States, residing at Colfax, in the county of Jasper and State of Iowa, have invented a certain new and useful Fountain-Pen, of which the following is a specification. I

The object of my invention is to provide a fountain pen of simple, durable andinexpensive construction of the class in which the ink reservoirjcomprises a flexible tube which may be compressed to exclude airand then when it expands it will draw ink into it automatically.

More specifically it is my object to 'provide improved means for compressing the flexible ink reservoir which means when not in use will lie, close to the outer surface of the pen holder cylinder so that it will not be in the way and so that it can not accidentally be pressed open to force out the contents of the flexible ink reservoir, and.

further to provide a device of this kind that may be quickly and easily moved to position where the operator can conveniently and easily operate it to compress the flexibleink reservoi My invention consists in certain details, in the construction, arrangement and combination of the various parts of the device, whereby the'objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a central, longitudinal,

sectional view of a fountain pen embodying I my invention, the cover plate and connected parts being shown intheir folded positions when the pen is being used' for writing. Fig. 2 shows an inverted-plan vlew on an .enlarged scale of the cover plate, the link being connected therewith and being shown in section. Fig. 2 shows a sectional view on the line [IF-[L of Fig. 2. Fig. 3 shows a detail, perspective view of the link forconnecting the cover plate with thecompressor plate. Fig. 4. showsan enlarged, detail, longitudinahsectional view of the pen holder cylinder with the parts in position for compressing the flexible ink reservoir; Fig. 5 shows an enlarged, detail, plan view of the compressor plate, and the link attached thereto. Fig. 6 shows an enlarged, detail, longitudinal, sectional view lllustratmga part of the pen holder cylinder and showing the ppsition that the cover plate assumes after 1t 15 moved rearwardly preparatory to using it for compressing the ink reservoir.

Fig. 7 shows a detail, top view illustrating a-port1on' of the pen holder cylinder and showing the coverplate in position at right angles thereto ready for use in compressing the ink reservoir, and Fig. 8 shows a sec tional view on the line 8+8 of Fig. 1 on an enlar ed scale.

Referring to'the accompanying drawings,

.1 have used the reference'num'eral 10,t0 indicate the pen holder cylinder which isof ordinary construction. At oneendthereof is the pen 11 and at the opposite end is a cap 121which may beplaced over a 'pen to conceal and protect it. On the interior of the pen holder cylinder is the flexibleink reservoir 13 preferably made of soft rubber .and connected at one end with a screw plug 1 through which communication is pro: vided to-the pen 11. These parts of the device are of the ordinary construction and operate inthe ordinary manner; that is to say, when the flexible ink'reservoir is compressed air will be excluded from it and then when pressure upon it is released andthe pen point is inserted in a quantity of ink the ink will fill the. vacuum within the ink reservoir by suction through the screw plug; 14 and the ink will be retained inthe ink reservoir' and will flow out through the pen in such quantities only asmay be used up by the pen point in writing.

My improved. means for compressing and,

releasing the flexible ink reservoir comprises a compressor plate 15 arranged within the pen holder cylinder and designed to engage the flexible ink reservoir. This compressor plate is provided with two lugs 16 spacedapart and a pin 17 is extended between them and fixed thereto. On'the same surfaceof the compressor plate is a top plug 18. The cover plate isdesigned to rest upon the exterior of the pen holder cylinder and is shaped to fit thereon and is indicated the numeral 19; i It is provided atits central portion with a lug 20, the sides of which are tapered as shown in. Fig. 8, and 1t is also provided at one end with a lug 20*,thes1des of which are tapered as shown-1n Fig. 2.

Thepen holder cylinder is provided with be inserted in themanner-shown in Fig. 4

and ilso to receive the link hereinafter .de- 11 10 plate with the compressor plate by means of a link 22, which link is provided at one end with two lugs 23 tapered at their inner surfaces as clearly shown in Figs. 3 and 8 to fit the tapered lug 20 of the cover plate. A pin 2a is lnserted through said lugs to thereby firmly connect them. The body portion of the link is made of resilient metal and is slightly arched as clearly shown in Fig. 3 and at the opposite end of the link is a rounded h00k-sl1aped portion 25 designed to encircle the pin 17. portion 25 is an extension 26 having a slot 26'' provided with tapered sides as shown in Fig. 2 designed to fit the tapered lug 20 By this arrangement it is obvious that the said link may be placed in position on the cover plate by sliding the link to position withthe lugs 20 and 20" between the lugs 23 at one end and into the tapered slot 26*" at the other end so that the single pin 24 will firmly hold. the link in position relative to the cover plate. The rounded end of the link stands close to the adjacent end of the cover plateso that the cover plate may swing on the pin 17 that is extended between the link and the cover plate to the position.

shown in Fig. 4; that is to say, at right angles to the compressor plate 15. The object of having" the central portion of the link arched is to have it frictionally engage with the pin 17 in such a manner as to preventaccidental longitudinal movement of the cover plate 19. Assuming that the cover. plate is in its closed position, as shown in Fig. 1, it "cannot be moved longitudinally of the pen holder without flattening out the arched central portion of the link and this furnishes sufiicient resistance to prevent accidental misplacement of the cover plate and yet the 7 cover plate may be moved longitudinally by the operators finger thereon in a direction tending to move the cover plate toward the outer end of the pen holder. Connected with the compressor plate at a point between the lugs 16 and 18 is 'a leaf spring 27 normally extended upwardly from the compressor plate at its endthat is adjacent to the stop plug 18.

Assuming that the parts are assembled in the manner illustrated and described, and assuming that the cover plate is in the position shown in Fig. 1, it is obvious that it will be firml held in position fiat against the surface 0 the pen holder cylinder on account of the arched link 22 engaging with the pin 17.0f the compressor plate wh1chobviously' will hold the compressor plate toward the adjacent side of the pen holder cylinder and at the same time hold the cover plate firmly in position against movement in any direction and as said cover plate is very thin and conforms-in shape to the exterior of the pen holder cylinder it will not in any On the hook-shaped I cease? end of the link in the manner shown in Fig.

6, then the cover plate is free to swing upwardly and the spring 27 will move it upwardly to the extent indicated in Fig. 6. In this connection it is to be noted that the function of the stop plug 18 is to engage the pen holder cylinder and prevent longitudinal movement of the compressor plate when the same is in position close to the interior of the pen holder cylinder. By thus having the end of the cover plate tilted'away from the pen holder cylinder by said spring, the operator may readily and easily grasp 1t and move it to posit-ion at right angles to the pen holder cylinder whereupon it may be used to force the compressor plate to the position shown in Fig. 4 and exclude the air therefrom to create a partial vacuum; then when the pen point is dipped in ink and the pressure upon the cover vplate is withdrawn the flexible ink reservoir will be filled with-ink.-

and the cover plate may then be swung to position parallel with the outer surface of the pen holder cylinder and moved toward the pen point to thereby again lockitin position by having the arched portionof the ervoir, and a cover plate pivotally and slidingly connected with the compressor plate,

and so shaped that when in onepositlo'n it may move longitudinally of the pen'holder to position with one end adjacent tothe widened portion of the slot and when in said position it may. be moved to position substantially at right angles to the pen holder 1 cylinder and be pressed downwardly through the widened portion of the slot, for the pur poses stated. 1
